illegal after-image journal format or journal incorrectly
  mounted

  Explanation:  The file you specified does not appear to be an
  after-image journal file.  For example, when performing an AIJ
  roll-forward operation using an after-image journal on a
  magnetic tape, this problem will occur if the tape is
  incorrectly mounted.

  User Action:  Check the file name and try again.  Verify that a
  magnetic tape was correctly mounted.
